 1   Public   Class  Hibernatecoreapitest {  2   Private   Static  Sessionfactory;  3       4   @ Beforeclass  5       Public   Static  Void  Beforeclass (){  6 Sessionfactory = New  Annotationconfiguration (). Configure (). buildsessionfactory ();  7   }  8   @ Afterclass  9       Public   Static   Void  Afterclass (){  10  Sessionfactory. Close ();  11   }  12       13   @ Test  14       Public   Void  Testgetstudent (){  15 Session session = Sessionfactory. getcurrentsession ();  16   Session. begintransaction ();  17 Student s = (student) Session. Get (student. Class , 1 );  18 S. setname ("XML" );  19   Session. gettransaction (). Commit ();  20   }  21 }

In this case, it will never work. In main

 
Public static void main (string [] ARGs) {beforeclass (); afterclass ();}
 

This can be found out.
